This study is using a community-based participatory approach (CBPR) to develop and evaluate an innovative culturally competent school-based intervention that provides substance abuse treatment counseling services to Native American Indian (Cherokee) adolescents. The study consists of a three year plan. Year One consists of strengthening and extending community partnerships and collecting data that will inform the development of the intervention for Years Two and Three. Years Two and Three consists of a two-condition quasi-experimental study in which the culturally competent intervention that provides substance abuse treatment counseling services delivered in the Native American cultural format of the Talking Circle is compared to standard care. Doctoral students have the opportunity to gain experience with the substance abuse treatment intervention services and the entire research process of the study.
